Configuring Amazon Route 53 for Google Apps

The moment I've setup Google Apps, I also purchased a domain name. At that moment Google configured this domain behind the scenes through Enom.

As described above and in order to get your static website up and running on S3, it is key to configure Amazon Route 53 as your Domain Name System (DNS). The how-to is described in detail in step 3 and 4 of the Amazons static website hosting walkthrough.

In case of a Google Domain name registration through Enom, your configuration will consist the following steps:

Go to the Google Apps Admin Console

Select Domains

Go to Advanced DNS settings

Follow the instruction to get access to Enom’s Domain Management

Change Enom’s DNS settings from Default to Custom

Fill in the DNS servers names copied from Amazon

By now your website should be online and accessible through your domain name. The only thing missing is the conversion of the MX records from Enom to Amazon’s Route 53. Without this conversion it will be impossible to deliver your domain’s emails.
